Qh'cZZ ac/1.0m it mag concern:

":Bc it known that we, ALEXANDER VVIN'roN and Harrow '13. Anonnson, citizcnsof the" United States, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful lm prove nients in Transmission-Controlliiftg Mecha- .nfism {or Motor-Vehicles, of which the following is a specification, reference being had therein to the accompanying drawing.

' This invention relates to improvements in transmission controlling mechanism for motor vehicles, am has relation to means and devicesi'or controlling what is. known in the art, as sliding gear transi'nission.

The particular type of sliding gear transmission with which the present inyention designed to cooperate is known as the selective type, and the object of the invention will be fully forth hereinafter.

in the accompanying drawin": Figure 1 is a view showing in side elevation a motor vehicle chassis which comprises our invention. Fig. 2 is an enlarged detached side elevation of the features involving the invention, a portion of the supporting case" thereof being-shown in section. vFig. 3 is an enlarged detached view of the coiiperating devices between the clutch pedal and brake lever.

Rotor-ring now to the drawings, 1 indicatcs the frame; '2 the engine; 3 the front supporting and steering wheels, and 4 the rcarfsupporting and driving wheels, all of be of the usual construction. he is well known, a single clutch is used for slicing gear transmissions of the lective? type, and so far as the present in vention is concerned any desired form of clutch may he used, and hence we do not show any specific form of clutch.

The clutch. pedal 5 is at the end of an arm (3, and this arm 6 is suitably supported to permit an oscillating movementof the pedal. All arm 34 is suitably connected to a clutch (not shown) which. is located in a clutch case 10. It is well known that in the form of clutch used with sliding gear transmissions, the clutch is normally held in 011- erative engagement by means of a spring or springs, and hence this need not be shown or When the clutch pedal is in the position shown in Fig.2, 1i is in operative engage ment, but when moved in the direction indicated by arrow in said figure, the clutch is moved out of operative engagement.

In the selective type here shown, there is employed a plurality of sliding rods 11,. I

and each of these rods is provided with a recessed member or block 12, with which the controlling lever 13 cooperates in a manner to be presently explained. Each rod carries a member 1 1 that is suitably connected with the sliding gear mechanism, but as this forms no part of the present invention, the transmission mechanism and the connection of the members 14: therewith is not shown, nor is it necessary to a full understanding of the invention by those skilled in the art.

The connection between the clutch pedal 5 and the clutch mechanism, as here shown, comprises alink 33 which has its upper end pivotally connected with an arm 34, and its lower end connected with a lever 31, which i. intermediatcly connected with a shaft 31".

his shaft 31. extends into the clutch case and is suitably connected (not shown) to the clutch members (not shown) for operating them.

The transmission lever 13 is laterally movable (not shown) as is well understood by those skilled in this art and carries with it an arm 18, the lower end of which. is adapted to engage with one of the blocks 12 of one of the members 11, to move it end wise for cont-rolling anism in a manner well understood. This transmission lever also carries with it a segment 4-1, which engages a sliding rod 38, and this sliding rod is constructed to lock the members 11, except the one that is engaged by thearm 18.

'Each of the members 11 is provided in its under side with a recess 26 and pivoted below these rods or membersis a spring latch 27, wide enoughand adapted to engage simultaneously the recesses 26 of all of the rods and lock them in their neutral positions, oi .the rods 11 can be moved by the trans} mission lever for controlling the gears of the transmission, the latch 27 must be disengaged from the recesses of therods. This latch is removably held in. the" recesses by an expanding spiral spring 28, which surrounds a rod 29, the rod having its upper end connected to the latch intermediate its ends, while the lower end of the rod is connected with the upper. end of the link 30,

as shown in Fig. 2. Before any the transmission mech- 10 ing the clutch lever to a trolling that mechanism,

spring detents or balls the operator can feel the engagement thereof.

31 of the lever being supported in an arm- 32, which projects from 5 When the clutch is in ment with the parts of the positions shown in Fig. 2, the latch is in locking engagement with the rods 11, and neither of them can be moved until the latch 27 is the casing 33.

operative engageforward position and thereby release the clutch, 'At the same ,time that the clutch is released the latch 27 is disengaged from the recesses 26 of the 'rods 11, thus permitting any one of them to 15 be actuated by a movement of the transmission lever 13.

From the foregoing it will be understood that the transmission controlling mechanism is locked when it is in a neutral posi- 2;) tion, and the clutch must be released before any of the gears can be put into mesh. So also, if the mechanism is operating through one series of gears it can not be changed without bringing the rod 11, which is contion. When it reaches its neutral position, the latch snaps into the recess of the rod and looks it. A slot 85 in the link 30 perits the latch to have an upward movement 30 independent of the lever 31, and independent of the clutch when the clutch is in operative engagement, sutficient to permit the latch to enter the ,recesses 26.

The rods 11 have recesses 36, in which 37 engage, so that when operating the transmission lever 13 and thus know when the parts are in proper position for the respective speeds.

A brake lever is connected with the clutch pedal 5, so that when the brake is This is aclink 56. The inner end of this link carries "a slotted member or yoke 53 having a roller 54 at its forward end. The shaft 51, to which the brake lever 50 is connected, car- 0 rice a cam 52, adapted to engage the roller released by mov-g .otally connected to its neutral p0si' 54 when the brake lever is in its applied position, thus forcing the link 56 forward, and

by this connection with the clutch pedal will release the clutch. When the brake parts are in theneutral position shown in Fig. 2, the slotted yoke 53 permits the clutch pedal to be moved into releasing position independent of the brake, a spring catch or trolling lever, a brake lever-shaft, a brake.

and a brake lever connected with said shaft, a cam directly carried by said shaft, a rearwardly extending link having one end pivwith the clutch lever and its opposite rear end having an elongated slot through which the brake lever shaft passes, the link having a cam surface engaged by said cam.

2. In a. controlling mechanism for 'motor vehicles, the combination of a brake, a brake shaft operatively connected with the broke, a brake lever, the brake shaft having a cam, an oscillating clutch pedal arm operatively connected with the clutch mechanism, a link having one end pivotally connected with the clutch pedal arm, the opposite end of the link having an elongated slot embracing the brake shaft, the link adapted to be engaged by said cam for operating the clutch lever, and the link having a movement upon the brake shaft independent of the cam to permit the clutch pedal to be operated inde-- pendently of the brakeshaft and its cam for the purpose described.

In testimonywhereof we ailix our signatures in presence of two witnesses.
